If you have the full path in A1 and the full new path in B1, put this formula in C1:
="ren "&""&A1&""""""&B1&""""
copy it down
now copy c1 to c whatever and paste it to command line. If using PAD:
Get Clipboard contents
Open CMD Session
Write to CMD Session using %ClipboardContents%
This will work much faster than doing 1 at a time using PAD.
